To all whom it may concern."

Be it known that l, NORMAN W. Now, a citizen of the United States, residing at Trenton, in the county of h lercer, State of New Jersey, have invented a Combined Electric lhamp Socket and Shade Holder, of which the following is a specification.

This invention relates to a combined elec tric lamp socket, including; the customary switch mechanism, and a shade holder, the two parts being so associated and assembled that the usual shell or casing for the lamp sockets may be dispensed with, the said. shade holder performing the function of a socket shell or casing, in addition to a support for the lamp shade.

The salient object of this invention is to provide a fixture of this type simple in design and construction and one that is very desirable from a practical standpoint, for the reason that the same can be cheaply produced.

Another object oil the invention is to provide a simple and eilicient means for sup porting or securing the switch mechanism to the nipple or the like usually employed for attaching the fixture to its supporting bracket or pipe section conveying the wires to the terminal point.

A still further advantage of this construction will be apparent, in that the means for securing the switch mechanism to the nipple also provides a simple yet substantial support for the shade holder.

The invention also contemplates the provision of a spacing member positioned be tween the lower end of the lamp socket and the lower end of the shade holder for positively positioning and always maintaining the socket and switch mechanism in its proper position within the shade holder, said spacing'member being so constructed that the same may be readily detachable.

Another feature of the invention is the particular means of supporting the spacing member within the lower portion of the shade holder adjacent the thumb screws employed for securing the shade within the holder, in such a manner that said screws may be entirely removed when desired to remove the shade, without disturbing or di placing the spacing members Briefly statechthe invention comprises the usual two part porcelain switch mechanism, including the screw threaded terminal for the eleetrie lamp, and a eemprisingan 1920. serial no. aaaaaa.

annular collar and downwardly and inwardly bent leg portions, the collar adapted to be swaged to the securing nipple or the like and the leg portions attached to the upper lace of the porcelain switch mechanism, which yoke construction forms a strong and rigid support for said switch mechanism. Completely enveloping the yoke and switch mechanism and forming); substantially a casing therefor is a shade holder having an enlarged lower end and provided with means for supporting in said lower end a lamp shade ot the usual construction. The upper or cap portion of the shade holder is sup ported upon and snugly embraces the yoke supporting the switch mechanism, said yoke forming; the double function of a support for the switch mechanism and the shade holder. Tnterposed between the shade holder and said switch mechanism is an insulating fiber shell or casing projecting downwardly and. also enclosing the screw terminal otthe electric lamp attached to the porcelain supporting the switch mechanism, Positioned between the lower end of this insulating shell and the lower end of the shade holder is a centering or spacing member forming a simple yet ellicient means tor positively positioning the insulating shell surrounding the switch mechanism, within the shade holder, the details of which will be hereinafter more fully set torth.

The invention embodying the several teatures above related is illustrated in the accompanying drawings, in which:

Fig. 1 is a View partly in section and partly in elevation, illustrating the preterred form of the invention with the shade holder made in two separable parts;

hleterring; to the drawings in detail,

lamp socket supporting vase made of? molded porcelain or similar insulating material, comprises the usual upper and lower sections 1 and 2, supporting therebet-wcen the switch mechanism 3 operated by the conventional key The lower section 2 has supported therefrom the electric lamp screw terminal 5 which is of the usual construction. Secured to the upper face of the porcelain 1, by screws or the like 7, is a supporting yoke provided with an annular collar 8 and a pair of downwardly and in wardly projecting curved legs 9. Collar S is positioned about and adapted to be swaged or similarly secured to a nipple 10 which nipple is of the usual type employer. for supporting the entire fixture from a bracket or the like. lVith this construction the entire lamp socket is securely and definitely supported from the nipple.

lompletely enveloping the entire switch mechanism and socket is a shade holder 11 which not only forms a support for the shade holder but acts as a shell or casing for the porcelain socket and thereby doing away with the usual metallic shell or casing generally employed with these sockets. The lower end of the shade holder 11 is llarer [outwardly and provided with an inwardly curved portion 12 which is adapted to receive and have secured therein the desired form of lamp shade, by thumb screws or the like 13, which thumb screws are threaded into bushings 14: secured in the curved portion 12 of the shade supporting end of the shade holder. Interposed between the shade holder and socket is an insulating fibe shell 15 which extends down below the *ew terminal 5 of the lamp socket, the lower end 16 being of less diameter than the upper portion thereof and thereby providing a shoulder 17, to behereinafter referred to. Positioned between the lower end 16 of the insulating shell 15 is a removable spacing member or spider 18. This spacingmember is formed with an upstanding annular collar 19 which is adapted to closely embrace the end 16 of the fiber shell, the upper edge of the collar abutting against the shoulder 17 which will prevent the displacement of the insulating shell. The spacing member or spider 18 is also provided with outwardly an d downwardly extending legs 20, the outer ends of which. closely (1171 017200 the inner :lacc of the lower edge oi the shade holder and rest on the bushings 14, which bushings provide a support for the removable spacing; member or spider. In order to insure a secure positioning of the spacing member 18, after once being adjusted, and to prevent the legs 20 from becoming disengaged from the bushings 14, a portion of the bottom edge of said legs are provided with recesses or curved out out portions 21, so that when the leg portions of the spacing member are snapped over the bushings, said spacing member will be secured thereon against. any accidental or unintentional displacement. When it is diulired to remove this spacing member-itisonlynecessarylo Force the some slightly to the rightor left, whereupon the legs of the spider will become disengaged rom the bushing and the same may he read ily removed from this assemliiled position. The husl'iings ll not only providc :1 Sl1ll stant-ial bearing for the screws 133, but by acting as supports for the removable spacing member or spider. the s-rcvcws lil may he l'reely manipulatiul. and in fact entirely withdrawn ii necessary in removing the shade, without disturbing the spacing: member or spider.

In one form of my invention, as illustrated in Fig. l, the shade holder 11 made in two separable sections and n'ovidcd with a rcmovable cap 11 the remaining: portion of the shade holdcr beingsecured thereto by snap catches or the like.

In the construction. as illustratrd in Fig. 7. the shade holder is made iu onc piece and also provided with a modified loi'n'i of spnc in; member between the lower end ofthe insulating shell and the shade holder. ln this construction tho shade holder is provided. with a screw threaded portion 22, which. adapted to engage complenn-ntnry threaded portioni- 2d, of an annular spacing member 24-. This sparing member 21 is constructed with a convcrhcd lower end 25 which closely embraces the lower end of the insulating Shell 15. it will. he noted that this spacing member is likewise removable, as is the spacing member illustrated in Fig. l.

is distinguished also from the construction of the shade holder illustrateil in Fig. l. clamping screws 13 may be. positioned in downwardly extending projections 13 formed on the lower end oi? the shade holder, as shown in Fig. T. In this construction the lower end 113 ol. the shade holder will not have to be made as large. relatively as the portion 12, as illustrated in l' ig. 1. wherein the clamping screws for the shade arc posi-- tioncd in the main part o this lower portion 12.

From lhc l'orcp iu; dcsi'ripliou it will he :1 ppareiii: that applicant has devised .I very simple. slvona'. and plnr'llcul combined lump socket and shade ho der, poill: 1 mini-- mum munhcr of parts. va'isilgi assembled and adiusljei'l. and a lislure that is not only cheap to manufacture hut comhiniu; therewith all the Features and ppcaramoot a linisllcd proi luct.
